Lesson 9 - Chapter 3: Application Problems Flashcards
What are 5 ways that application problems show up?
- Won’t install
- Won’t start
- Won’t uninstall
- Locking up or crashing
- Version incompatibility hinders performance
When the clock settings in Windows aren’t right, what kinds of issues can it cause? (3)
- Application won’t run
- Application reports false errors
- Anti-ware software will report out-of-date definitions for clocks set to the future
What causes the BIOS/UEFI time and settings to be off?

What are the 2 kinds of apps that we learned in lesson 2? What do these 2 apps require to install?
- Microsoft Store apps (install automatically when downloaded from the store)
- Desktop apps (require a Setup utility to install like disc, USB drive, download)
What are 4 reasons why a Setup utility doesn’t work?
- Not
- the Setup
- the app
- PC doesn’t
- Not signed in with an Admin account
- the Setup file is corrupt (error during download). Re-download it.
- the app is incompatible with the current Windows version. Use compatibility wizard.
- PC doesn’t meet minimum requirements, verify, update drivers app will use
Why when you connect an optical disc or USB flash drive to install an app, does the Setup utility launch automatically?
because a file named autorun.inf is on the disc
Why is autorun.inf (AutoPlay) a security risk?
someone could put malicious programs on removable media and the autorun.inf file could point to the virus to run automatically
How do you disable AutoPlay? in Win10 and Win11
Win10: Settings > Devices > AutoPlay
Win11: Settings > Bluetooth & devices > AutoPlay
When an app won’t start, what’s the first question to ask?
Did it EVER start? (Is this the first time installing it?)
What are 5 things to try when an app you just installed won’t start?
- R
- Confirm
- Confirm
- Confirm
- Visit
- Reboot (may need to load something at startup to start)
- Confirm system meets the app’s minimum requirements
- Confirm the OS is supported by the app (old apps try compatibility mode)
- Confirm compatible display adapter with latest drivers (common issue with games)
- Visit the app’s website, check the Support section for help
What are 3 things to try to troubleshoot an app that used to work fine but has stopped working?
- 3 steps

What are 2 places an app should appear?
- Settings > Apps > Installed Apps
- Control Panel > Programs > Programs and Features
What’s the single biggest problem with uninstalling an app?
People try to uninstall without admin privileges (logging in as an admin should be fine)
What if an app won’t uninstall because a part of the app may be running in the background?
Open Task Manager and end the process there, then uninstall
What’s a more thorough way of making sure no processes related to the app are running? Why?
Booting in Safe Mode and uninstall from there (because Safe Mode doesn’t run unnecessary processes at startup)
What does Microsoft have that can help install/uninstall an app?
Microsoft Install/Uninstall Troubleshooter
What’s the downside of using System Restore to return to a version of the system files that was before the installation of the app? (2)
- Can uninstall any other apps you’ve installed since then
- It doesn’t delete the app files from the drive just the reference to it from system files
What are 2 issues that can prevent an app from uninstalling?
- Uninstalling without admin privileges
- Part of the app is running in the background
What is CTD?
Crash to Desktop
For example, what are 2 issues that poorly-written, rushed, error-prone codes for apps can cause?
- Computer locking up
- System shutting down unexpectedly (and cause errors to files/folders)
Keep in mind that a computer crash can be caused by what 3 things?
- Hardware problems
- Driver problems
- Application problems
What’s a good tool to troubleshoot application crashes?
sfc /scannow (because an app crash can sometimes be caused by a bad system file)
What could be the problem if you’re playing a graphically intense game but the screen and Windows lock up? (3 possibilities)
{RAM intensive}
- The app ran a routine that clashed with another app or a Windows feature was used improperly
- Video card failed from being overtaxed
- The system accessed a bad section of RAM
What if a graphically intense game degrades the overall performance of Windows?
If the computer can run other apps fine, then it points to it being an application issue rather than the hardware or drivers

How far back does Window’s 11 Compatibility mode go?
Win11 Comp mode supports Windows Vista and later
How far back does Window’s 10 Compatibility mode go?
It goes back as far as Windows 95
